New Video: Madman's Timeline To Kill Cops

New Video: Madman's Timeline To Kill Cops

The assassinations of two New York police officers gripping the nation started in a suburb of Baltimore.

On Saturday at 5:48 a.m, 28-year-old Ismaaiyl Brinsley shoots his ex-girlfriend in the abdomen.

6:30 a.m: Baltimore County police track Brinsley by a cell phone going North on I-95 on a Bolt Bus.

10:50 a.m: He's seen on video getting on the N train subway near Times Square and heads to Brooklyn.

1:30 p.m: Brinsley starts posting ominous threats on Instagram.

He posted a photo of his gun with a message, “I'm putting wings on pigs today. They take one of ours. Let's take two of theirs. #ShootThePolice #RIPEricGarner #RIPMikeBrown this may be my final post I’m putting pigs in a blanket.”

Then this post: “Never had a hot gun on your waist and blood on your shoe.” The location of the post was in Brooklyn.

2:10 p.m: Baltimore cops faxed a wanted poster to NYPD that said: "The suspect is armed with a 9mm handgun and has posted pictures of the handgun on Instagram saying that he will shoot a police officer today.”

But the warning comes too late, 37 minutes later at 2:47 p.m. Brinsley approached two strangers and said, "Watch what I’m going to do." Then, he walked over to officers Wenjian Liu and Rafael Ramos who were sitting in their patrol car.

A video posted online was shot moments after the incident hears people screaming, “This is crazy! Two cops just got shot in the head!”

Brinsley fled to a subway a block away. He was cornered by cops and shot himself.

Cell phone video posted online was captured by a man on the subway as police order everyone to lay on the ground as they try to make sure the situation is under control.

Chaos flowed onto the street as two ambulances arrived for Officer Ramos and Officer Liu.

NYPD Commissioner Bill Bratton said in a press conference, “They were, quite simply, assassinated. Targeted for their uniform and for the responsibility they embraced to keep the people of this city safe.”

First responders carry Brinsley's corpse out of the subway.

Brinsley has been arrested 19 times. Three months ago he documented one arrest in a series of Instagram posts stating: “We don't respect the pigs. That's why the camera is in his face.”

A video from Brinsley's Facebook page shows that it appears he's being confronted by a K-9 unit. The disturbing postings now seem like eerie signs of what was to come.
